是被动语态。 要注意的是：把主动语态的谓语变成被动语态的be+ 过去分词，时态要与原句保持一致。 They will build a new bridge over the river. (主动) A new bridge will be built over the river. (被动) My aunt invited me to her dinner party. I was invited (by my aunt )to her dinner party.
be done是被动语态的一般形式。在不同的时态中，被动语态有不同的构成，其中基本结构就是be done，be 动词加行为动词的过去分词。
be done是被动语态，不是时态。 且be done一般表示被动语态中的一般现在时态。 以下是被动语态的几种时态： 1、一般现在时态：be(am is are) done 例句：I'm taken to school by my father every day。
(我父亲每天送我上学。) 2、一般过去时态：be(was were) done 例句：I was taken to school by my father yesterday。(我父亲昨天送我上学了。) 3、一般将来时态：will done 例句：I will taken to school by my father tomorrow。
(我父亲明天要送我上学。) 4、过去将来时态：would done 例句：Flourish said that he would taken to school by my father tomorrow。(弗罗伦斯说他父亲每天送他上学。
) 5、现在进行时态：be(am is are) being done 例句：I'm being taken to school by my father now。(我父亲正送我上学。) 6、过去进行时态：be(was were) being done 例句：I was being taken to school by my father at that time。
(我父亲那时正送我上学。) 7、现在完成时态：have(has) been done 例句：I have been taken to school by my father every day for three years already。
(我父亲每天送我上学已经三年了。) 8、过去完成时态：had been done 例句：I had been taken to school by my father every day for three years yesterday already。
(我父亲每天送我上学到昨天已经三年了。) 9、将来完成时态：will have been done 例句：I will have been taken to school by my father every day for three years tomorrow already。
